Glitch with Windspeaker's Blessing and Runic Armor?

I was playing a game as Urgot and I found that my W Terror Capacitor shield was not getting a benefit from the two masteries. Based on the way they are written, "Windspeaker- Your shields are 10% stronger" and "Runic- Bonus to shields on you", it implies that all shields should work, even self shielding. Is this intentional or a glitch? I tested both, and both individually and didn't get a bonus.

Also somewhat related, Perseverance is written as +50% bonus health regen (and 200% under 20% HP), but it only impacts base health regen, like healing beads do. Probably intended, but I could see how it could get confusing since you can increase your flat (flat but not base) health regen with runes.
